Multiple upload file with PlayFramework

Question

I'm trying to upload multiple files at once with Play Framework, but I always get the first image for each uploaded. Here's a concrete case :

The HTML :

<form method="post" action="/upload" enctype="multipart/form-data">
    <input type="file" name="image" />
    <input type="file" name="image" />
    <input type="file" name="image" />
    <input type="file" name="image" />

    <input type="submit" name="submit" value="Send images" />
</form>

The controller :

public static void upload() {
    File[] images = params.get("image", File[].class);
    for (File f : images) {
        Logger.info (f.getName());
    }
}

If I upload image1.jpg, image2.jpg, image3.jpg & image4.jpg, the Logger.info on the console will display :

image1.jpg
image1.jpg
image1.jpg
image1.jpg

The other images won't be used.

I tried with List<File> instead of File[] but it doesn't work neither.

I also saw there is kind the same question here on SO (here), that use this as an answer :

List<Upload> files = (List<Upload>) request.args.get("__UPLOADS");

But it doesn't work in the v1.2.4 of Play!.

I'm using Play v1.2.4.

Thank you really much for your help!

Answer 1

Well, I have opened a ticket at Play! Framework because it seems to be problem, and apparently, I'm not the only one to have this behavior.

I tested with the new 1.2.5, and the problem is fixed, at least with the solution I gave on the question :

public static void upload() {
    File[] images = params.get("image", File[].class);
    for (File f : images) {
        Logger.info (f.getName());
    }
}

Note: I'm using Java 7!
